GMDS - I disagree with the core of your statements.
To gain control of the Airbus in an unreliable airspeed/data scenario (ie pitot or static ports/sensor fault) you...
Disconnect autopilot (if engaged) by pressing red button on sidestick
Switch off flight directors
Disconnect autothrust press button on side of thrust levers
Pitch and Power to memory drill datums
It won't pitch up erroneously in manual flight.
How do other aircraft differ?
I am in no way making inferences about the actions of the crew in this scenario, just highlighting that the Airbus is as safe as any other jet with unreliable air data.
